An understanding of precipitate size distribution and its evolution with processing conditions is important with regards to the final mechanical properties of microalloyed pipeline steel. A study was undertaken using small angle neutron scattering (SANS) to quantify the size distribution of nano-sized precipitates in X80 pipeline steel. The distributions obtained for different X80 samples were correlated with the finish rolling temperature and final coiling temperature as a means of identifying processing conditions that may enhance fine precipitate evolution. The precipitate distribution predicted for Grade 100 steel using SANS data is compared to data obtained from a TEM particle counting analysis.
